Yeah, there are lots of similarities to Vertical Paxos. It also shares a lot van Renesse and Schneider's classic Chain Replication paper (https://www.usenix.org/legacy/event/osdi04/tech/full_papers/...), with the use of a configuration master to configure a chain that can't solve uniform consensus by itself.

That's not a criticism at all, though. There are a lot of good design and systems ideas there, and they are well explained in this post.

I'm glad you enjoyed the post. The chain replication work indeed relies on a paxos-based master service for reconfiguration, but I believe that's the only similarity, the replication scheme is different otherwise.
